To create a minimal Docker image for production Go services, use a multi-stage Dockerfile that builds with golang:1.26.2-bookworm and deploys to a gcr.io/distroless/static:nonroot runtime for a small, secure image.

A distroless Docker runtime is a minimal container image containing only your application and its runtime dependencies, without package managers or shells. You need it for production to reduce attack surface and image size.

Yes, you can run Docker containers as a non-root user by using a runtime image like gcr.io/distroless/static:nonroot. This prevents privilege escalation attacks and enforces secure production deployment practices.

Yes, this Docker configuration supports CI/CD pipelines by accepting environment-configurable build arguments, enabling layer caching and static linking for reproducible, optimized production builds across different deployment environments.

Distroless images lack a shell and package manager, limiting interactive debugging and runtime dependency installation. You must include necessary certificates and configurations during the build stage rather than modifying them at runtime.
